Professional Greenhouse Water Soluble Fertilizers

Proven Winners® Professional Greenhouse Water Soluble Fertilizers are designed to improve pH management and minimize problems due to high pH levels.

Proven Winners® has developed four specific formulations to minimize and correct pH related problems at different water alkalinity ranges, as well as cold weather growing and greening formulas. Each formula contains 100% FeEDDHA, the best ch-elated Iron form available, for improved plant Iron uptake at high pH levels and to correct Iron deficiency.

Formulated for Proven Winners® and Proven Selections® Plants and to Match Your Specific Water Supply

One of the most frequently asked questions of Proven Winners® from growers across North America is how to best manage plant nutrition and pH. Based on the questions we receive, we know that incorrect fertilization and pH is a leading cause of grower production issues leading to less than optimal results.

Because of this, we have developed Proven Winners® Professional Greenhouse Water Soluble Fertilizers:

These products are developed to work at different water alkalinity ranges in order to help minimize pH-related problems.

Based on review of a recent water test from your greenhouse or nursery, Proven Winners® will recommend one of four formulations targeted at specific water alkalinity ranges to help minimize pH-related problems.

There are also products for cold weather growing, as well as a greening formula.

The Iron source in each product is 100% FeEDDHA, the best ch-elated Iron form for plant uptake at higher pH levels.

The specific formulations of Proven Winners® Professional Greenhouse Fertilizers were developed by our own growers for results in different growing conditions. Plus, they are backed by the advice and service of the Proven Winners® propagator companies.

We'll Use Your Water Test Results to Help Select the Right Product for You

Which Proven Winners® Professional Greenhouse fertilizer is best for you to use is based on water test results. If you have a completed water test that is three months old or less, send the results to your Proven Winners® propagator. If you don't have a test kit, call your Proven Winners® propagator and they will send one to you. Once complete, send the results to your Proven Winners® propagator. When they receive your test results, they will then recommend the proper products based on your specific water test results.
